Patent EP-0171143-B1 (EP)
IPC: F04F1/18
Filed: 1985-06-04
Granted: 1990-05-23
Abstract: A pump (10) is provided with a vortex generaing member (35) which rotates about a central axis (32) to generate a vortex column (30) of liquid which has a rotary velocity and which is directed to the pump inlet (15). At the pump inlet, this energy is dissipated into the ambient liquid (16) causing an inward flow of liquid swirling in an opposite direction into and through the pump inlet (15) for discharge through a pump outlet (18). The preferred vortex generating member (35) has a plurality of outer liquid inlets (42) leading to passageways (48) of reducing cross section which causes the liquid to increase in velocity as the liquid flows radially inwardly toward the axis (32) and liquid streams are combined tangentially at the axis. The pump is particularly useful for pumping liquids with particulate content and overcomes the problem of abrasion between moving parts by such matter.

Title: Processeur numerique pour signaux radar capable d'executer la suppression adaptative d'echos parasites par un estimateur parametrique
IPC: G01S13/524
Filed: 1985-07-03
Granted: 1991-04-17
Abstract: Un processeur numérique de signaux radar peut exécuter la suppression adaptative de perturbations causées par des échos parasites et amplifier le signal utile ayant une fréquence Doppler donnée; il est en outre proche du principe d'opération du processeur optimum, qui est celui qui maximise le rapport signal-bruit. Ce processeur peut également annuler, de manière adaptative, un composant d'écho parasite ayant un spectre de puissance approximativement Gaussien. Il a une meilleure performance qu'un indicateur de cible mobile ou qu'un indicateur A de cible mobile suivi d'un intégrateur cohérent. Il comprend un estimateur (4) (voir Fig. 3) des paramètres de perturbation, qui traite des signaux (B) en provenance des cellules de portée du radar adjacentes à la cellule A d'où provient le signal destiné à être filtré. Une mémoire (5) est partagée en un nombre donné de zones, dont chacune (C, par exemple) contient des informations relatives à une perturbation spécifique due à des échos parasites; sur la base des paramètres estimés par l'estimateur (4), la zone spécifique relative à la perturbation réellement présente est sélectionnée. Ces informations numériques (C) sont transférées dans un tampon (registre de transit) (6) et traitées dans un "synthétiseur de pondération" (8) avec les échantillons attendus de signaux qui sont conservés dans le registre (7) et avec un paramètre supplémentaire relatif à la fréquence moyenne d'échos parasites, en provenance de l'estimateur (4). Les pondérations appropriées relatives à la suppression d'échos parasites sont obtenues et conservées dans un registre (9) qui à son tour commande un filtre (10) de réponse à des impulsions limitées.

Title: Method and apparatus for preventing deposition of coating material on a spray head
IPC: B05C7/02
Filed: 1986-01-25
Granted: 1990-11-28
Abstract: To prevent a formation of aerodynamic dead zones in a coating arrangement for powder coating, such as, for example, weld seams, a surface of a supporting member is provided with a constantly increasing radius of curvature between an outlet orifice for a spray jet and an exhaust orifice, starting with the former. A feed conduit is fashioned so that a laminar flow of the coating medium does not experience a change in an arithmetic sign of its path of curvature in the orifice zone and along a subsequent surface. For a constant acceleration of the spray jet, a constant reduction of the flow cross section is provided for the spraying medium between the outlet and the exhaust conduit.

Abstract: This invention teaches a process for preparing a conjugate useful in enzyme immunoassays, and the conjugate produced by the process. The process involves oxidizing an enzyme containing a carbohydrate portion, such as peroxidase, with periodic acid or an alkali metal salt thereof in an aqueous medium followed by reduction with sodium borohydride. The oxidation and reduction step may be carried out either before or after the enzyme is coupled to the immunologically effective component of the conjugate.

IPC: C07C45/50
Filed: 1986-09-18
Granted: 1989-11-15
Abstract: The present invention relates to a process for the preparation of aldehydes by the reaction of olefinic compounds with hydrogen and carbon monoxide in the presence of a catalyst system containing rhodium and aromatic phosphines. The aromatic phosphines are soluble in organic media and represent salts of sulfonated or carboxylated triarylphosphines which are insoluble in water. After hydroformylation, the reaction product is treated with a diluted aqueous solution of a base and the aqueous phase containing rhodium and aromatic phosphines is separated. Thus, thermal loading of the catalyst, for example by the redistillation of the reaction product, is avoided.
